Why do I get a blank SSO screen when attempting to sign in to MATLAB at start up?
I was able to install MATLAB, however I am not able to sign into my MathWorks Account with my university credentials when trying to launch MATLAB for the first time.
When I input my email address it says I must log in through my school’s portal, but nothing pops up except a blank white page in my shortcut.

Determine the direction of travelling waves in Fourier Analysis

% wave. Please, how do I determine the direction of the travelling waves?
% Compute the phase of the FFT: theta_phase = angle(Ytheta);
% Compute the mean phase difference: p = polyfit(f, theta_phase, 1);
% slope = p(1); % The slope of the phase vs. frequency plot
% Store the mean phase difference: mean_phase_diff(i) = slope;
% Then I test the mean_phase_diff(i) > 0 implies rightward direction or if
% mean_phase_diff(i) < 0 leftward direction. I am wondering if there is a

How to obtain the State Transition Matrix from Simscape Multibody model?
I need to include the Dynamic of the robot I’m using, imported from an URDF file, to a Extended Kalman Filter as the State Transition Function in order to estimate the states of the system. I tried to put all the simscape model inside a Simulink Function, but it brings Error1 saying I can’t put the solver configuration block (from the robot’s body tree) inside a subsystem. I came back and also tried taking the solver configuration block out of the Simulink Function and brin it in using a Connection Port, but it sends now Error2 saying all the elements of the body tree must be in the same level.
Error1: "’brazo_2dof/Simulink Function/Solver Configuration’ has been placed in the function call subsystem ‘brazo_2dof/Simulink Function’ but does not support this configuration. Move the block out of the function call subsystem."
Error2: "Connections of the Physical Network cross nonvirtual boundaries. If any blocks in a Physical Network are within a nonvirtual subsystem, then all blocks of that network must be in the same nonvirtual subsystem. Either move affected blocks out of the nonvirtual subsystem, move network blocks into exactly one nonvirtual subsystem, or reconfigure affected nonvirtual subsystems to be virtual subsystems."

Microsoft office outlook cannot connect to onprem exchange server
Hi,
In my company, we are using on-prem Exchange 2019 for the mail server and we published our main website on the same domain as the primary email address. For instance, email address removed for privacy reasons is our email address format and our website address is example.com. Everything was working fine until we developed our website, after that from the internet whenever I tried to add an account to Microsoft Office Outlook I kept receiving “Something went wrong and Outlook couldn’t set up your account”. After so much effort and searching I’ve found out the reason is that Outlook sends a query to example.com which is my primary domain and the new website sends some response that causes the error and when I removed the DNS record from the internet everything went back to normal.
Now I do not know how to resolve this issue so I can have my website while outlook works correctly.

Onedrive – why multiple folders in Explorer
OK I know many folks don’t like OneDrive, but I have 2 PC’s and a laptop, and I want files and emails to be available on either device.
Now that I found out how to stop my desktop being copied between the units that all have different display size and resolution, OneDrive basically lets me do that.
However, it presents an annoying feature whereby there are 2 different branches with folders on my primary PC.
There is a one drive folder – in John -Personal and John Chapman, the problem is I then see multiple downloads, document, picture folders etc, which confuses me.
How do I simplify this – I create Word, Excel and PowerPoint files and use outlook for 2 email addresses – those are the files I want available on either of the 3 devices I use.
Is this duplication or just a view selection that I don’t know how to control?
Did I describe my problem clearly? It’s hard to show full detail without showing more folder content.
Thanks.

2. If I create the MSIX using our company’s publisher details, the MSIX installs and launches successfully. However, it does not upload to the Apps and Games section, displaying a publisher and certificate-related issue.
